# CLI Always make sure to run the CLI as ADMIN to avoid any possible errors! You can start multiple CLI instances.\ If you do it you will see that just one will be considered as **Master**, other ones will be considered as **Peer**. ### Master instances Are responsible of accepting quicktasks, serving our built-in harvesters and coordinating your browser instances with all utilities we always offered. If you need to mirror a link, bootstrap your chrome instances at once and do what you are used to do with our CLI just run it here. ### Peer instances Also considered as standalone ones, are simple instances that will run CLI modules.\ They are context isolated. They will not comunicated with any chrome extension running on your instances. Consider them like continers that can only run tasks. Nothing more. *** {% hint style="warning" %} On Windows, as soon as you open the CLI a popup appears by asking you if the app "driver.exe" can access your network: **please allow it** or CLI modules will not work! If you - by mistake - denied the network access please head to:\ \- Settings\ \- Privacy and Security \ \- Firewall\ \- Allow apps via firewall\ \- Scroll into the list and search for *driver.exe* and manage his permissions by allowing it to access your network {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
